Okay, that's enough... i've seen plenty of SLIDERS_For&Against that i absolutely must give my opinion on the controversial process.
It's good as is to me, since i can actually prioritize anything at 100% while both others can move to 0% or_between_less_more to 50%, cuz that's what the integral countdown sets forth to get a real TOTAL_EmpireWide_Centralistic_Coherent_Definitive value.
Production/Research/Social (three concepts, variable in meanings to some and yet obvious logic to many more!).
Why is it so hard to "understand" (not sure about that exact word)
- that the **Global Control** pattern has to be present somehow
- that it also doesn't enforce anyone into a pre-set management towards Manufacturing(x2 types) OR Research in any way other than what they HAVE to decide sooner or later by properly developping key assets
- that it wouldn't, in as far as i can evaluate mathematically, provide a different spending or wasting edge in all three major areas if they were maxed out to a full 300% (indirectly) total as a whole
- that when i want to alter the variations at the planetary level (Which IS the whole empire numbers too, btw) i just pay the spreadsheet with my presence and floods it with any focus buttons locked into just *

simple columns (Logos & all to hint me about the consequences for me to grasp by looking sharp at any) as i please -- all at once!

0%+15%+85% is always equal to 100%. This metaphor will never let anyone abstract the Laws of Intelligence beyond reality.
Multiply_Divide, cope with it.
Break that very maximum value, and you're in for a nightmarishly different game altogether including a Macro(the biggy type, ya know)-Managing loop hole so daunting you'd instinctively rush for a QUIT permanent button within 20 minutes of trying to handle that much decisions never to return again to this game unless someone brought it right back with the excellent actual balance - asking for y_our begging smiles.
So, there.
Off my soap box.
Keep the sliders or change them, SD.
The risk is still yours to take, but if the above theory didn't convince anybody, nothing ever will.
Sorry about
sliding away from the 1 to 5 suggestions schema.
I had to.
